I try to translate this plugin, i found a little textdomain mixing (wpmudev ) and some gettext usability problem (Report This $object_type can't recognized) and some missing UI translation. And some date() date_i18n() using problem.
I make a dirty patch (WARNING: This patch contains a part of modification the moderation report link generator because plugin version 1.0.4 and wordpress 3.2 will not work together. WP_ADMIN check removed this is not internationalization patch, this is usability modification)
If possible apply include this patch. Thanks
